Saltalamacchia's average hasn't been this high since his rookie year, when he hit .266. But you don't add him for his average -- you chase his power. Last year, Saltalamacchia hit 25 home runs in 405 at-bats, which followed a 16-homer season (over 358 at-bats) in 2011. His five this year put him on pace for about 20 home runs, but for Points league players, Saltalamacchia could also be a nice source of doubles, with 10 so far (good for sixth among catchers). 

His ugly April may have turned some owners off to adding him, but Saltalamacchia's strong May should open some eyes. Owned in 39 percent of leagues, he could make for a nice power source in deeper one-catcher formats. 

"Martin is a very good baseball player and he certainly has the ceiling to get better," Washington said. "How good? I think we'll just have to wait and see."

Martin continues to split playing time in center field with Craig Gentry as he learns how to adjust to a 162-game schedule. However, his playing time has been on the rise lately because his offensive production has taken off. Martin has started eight of the last 10 games through Wednesday and has hit safely in seven straight (.381).

Still, Washington feels Martin has plenty of room to improve offensively.

"I think he's still trying to find that," Washington said. "The thing is he's getting comfortable and getting his confidence together, and that's the key."

Davis is batting just .147 with a .482 on-base plus slugging percentage through the season's first 42 games, and rumbles about a possible demotion are growing louder by the day. He is 1 for his last 38 to drop him to last among qualified hitters in batting average. 

Pena has been on a roll offensively, hitting safely in four straight games and six of seven. He's batting .423 (11 for 26) with one double, two home runs and seven RBI in his last seven games.

"There's no other options," Maddon said, per The Tampa Tribune.

LeMahieu has never hit below .314 in any of his five minor league campaigns (he has a .321 career minor league BA). In 306 major league at-bats, he has a .294 average. I wouldn't expect much in the way of power or speed from LeMahieu, but 20 doubles the rest of the way (assuming he gets regular at-bats) wouldn't be out of the question, and you can pretty much bank on the average to be there. 

In NL-only, he's a must-add. But I would consider adding him in formats as shallow as 15-team Roto leagues (at MI or UT), based on his promise in batting average. 

Santana had just his third multi-hit game in May Wednesday. He's batting .200 (14 for 70) with three home runs, four doubles, six RBI, 12 runs and 13 walks in 20 May games.

Cabrera is batting .273 (21 for 77) with a .506 slugging percentage, a triple, two home runs, 10 RBI and 11 runs in 20 May games.

Brantley is having a productive May, batting .338 (25 for 74) with a home run, a double, 10 runs and 15 RBI in 21 games (18 starts).
